“If ever a book found words for cosmic energy, it’s THE THRESHOLD OF LIGHT. ‘Light’ becomes the dynamic force here; and in this sallow time in history we need this book more than ever. To live at the highest level of human thought is to refresh language; and Glaser shows that our ordinary daily acts are divine ones. This poetry blesses every day, and us, with its descriptions.”—Grace Cavalieri, The Poet and the Poem from The Library of Congress
